The first collisions of #LHCRun3 🤩

In this #PhotoOfTheWeek, take a look at the first high-energy collisions recorded by the LHC's @ATLASexperiment, @CMSExperiment, @ALICEexperiment and @LHCbExperiment, as well as other experiments, such as @FASERexperiment and SND. 👇

Display of a collision event recorded by ATLAS on 5 July 2022, when stable beams of protons at the energy of 6.8 TeV were delivered to ATLAS for the start of #LHCRun3.

Display of a collision event recorded by CMS on 5 July 2022, when the collisions at the record energy of 13.6 trillion-electronvolts (TeV) were first recorded by the #LHC experiments. #LHCRun3

1/ Guida rapida per decodificare le informazioni che vedrete domani durante la diretta delle le prime collisioni protone-protone a 13.6 TeV. L’acceleratore #LHC segue delle fasi, ogni fase è definita da due parametri: ACCELERATOR MODE e BEAM MODE. #LHCRun3 #CERN
2/ L’ACCELERATOR MODE indica lo stato generale della macchina. Per esempio negli ultimi 2 anni è stato SHUTDOWN perché l’acceleratore era in manutenzione. Un'altra modalità è quella di MACHINE DEVELOPMENT usata dagli operatori di LHC per i loro studi di performance.
3/ Domani l’ACCELERATOR MODE sarà PROTON PHYSICS ossia nella modalità di produzione di collisioni stabili protone-protone. I controlli di LHC sono estremamente complessi in queste settimane il lavoro è stato proprio quelli di trovare le importazioni giuste per PROTON PHYSICS!

Today’s #PhotoOfTheWeek is all about the @LHCbExperiment. We are almost ready for #restartingLHC, so here are some of the tasks involved in the upgrade of the LHCb experiment. 💪
@LHCbExperiment ✅ Upgrade of the VErtex LOcator, a detector used to determine the exact point where the particles collide. One of its sensors is just 5mm away from the beam. Brand new modules were installed, with 40 million active pixels.
@LHCbExperiment ✅ New mirrors for the ring-imaging Cherenkov (RICH) detectors: this system consists of two huge digital cameras that measure the speed of particles. The lens system of the cameras is made of about 200 flat and spherical mirrors immersed in special gases.
